The council alleges misleading or harassing phone calls in those ridings kept some people from voting and may have affected the outcomes.

The law lets voters legally challenge the results in their ridings. If a judge finds anything that would have changed the outcome, a new byelection can be ordered.

Such decisions are extremely rare. But last week, an Ontario judge ruled enough suspect votes were cast due to clerical errors to warrant overturning last year's election result in a Toronto riding, where Conservative MP Ted Opitz beat Liberal Borys Wrzesnewsky by a mere 26 votes.

If the ruling stands, a byelection will have to be called in Etobicoke Centre.

But the Conservative lawyers argue there's no proof anything similar happened in the seven ridings up for election review.

"There is nothing in this application that remotely rises to proof beyond a reasonable doubt," the motions say.

"As stated above, the applicants have failed to put forward even one instance where an elector was denied the right to exercise her or his franchise.

"Instead, rather than provide the material facts necessary to sustain a successful election challenge, the application relies upon generalized allegations of 'voter suppression.'"

The Council of Canadians accused the Tories of trying to keep the so-called robocalls affair under wraps.

"These motions are nothing more than an effort to dismiss the democratic rights of individual Canadians," executive director Garry Neil said in a statement.

"If the Conservatives really want to get to the bottom of the robocalls scandal, they would be keen to have these cases heard and decided. Instead, they are bringing entirely meritless motions to prevent that from happening."
